I thought I read somewhere that the Ruthenian and Ukrainian Catholic Churches are not distinguished outside of Ukraine and the US and that in other places, such as Canada or the UK they simply all fall under or go by UGCC. Is that true and if so, does that mean someone who is Ruthenian in the US and moves to say Canada becomes Ukrainian at least while in Canada? And what about children say two or three generations later if they were to come back to the US do they then come back under Ruthenian jurisdiction?
I don’t know why I was thinking about that, but I just wondered.
The canonical “Ruthenian” Church comprises a total of 6 hierarchs; a Metropolitan and 3 Eparchs in the US, and an Eparch and an Exarch in Europe. The Eparchy came into union separately from the UGCC.
Outside the US, those whose canonical enrollment is Ruthenian are usually entrusted to the local Byzantine hierarch, failing that, to the territorial ordinary of the place (usually Roman). Where (Canada, England, Australia, etc) there are multiple Byzantine hierarchs, the UGCC is the preferred choice.
The Ruthenians in the US are mostly descendants of expatriates from the Subcarpethian Rus. Their being made an eparchy was a matter of protecting them from Latinizations and oppression by the Roman Bishops of the US.
Canonically, Muchachevo is the “home base” of the Ruthenian Church, but the majority of the faithful are now in the US, and have been for decades. The Czechs are also canonically Ruthenian. The Eparchy of Muchachevo and the Exarchate for the Czech Greek Catholics are autonomous from the Metropolitan of Pittsburgh, but still canonically are part of the same Sui Iuris Church.
Likewise, when in the Eparchy of Muchachevo or the Exarchate for the Czechs, Ukrainians, Belarusyns, Melkites, and other byzantines are under the canonical care of the local Ruthenian Bishop…
The overlapping jurisdictions of particular byzantine churches seems to be an english-speaking world phenomenon.
